United States Patent 3,191,494 COMBINED PHOTOGRAPHIC TRANSPARENCY ANDSTATIONARY SPIRAL-SHAPED SOUND The present invention relates to meansfor rendering the viewing of photographic transparencies or slides moreinformative and enjoyable.

Photographic slides may be directly viewed through a viewer or projectedby means of a projector. The invention is primarily concerned with thelatter method of showing slides which is generally the more elfectiveone. w While a projected slide image, as any picture, is to a certainextent self-explanatory, additional information or comment pertaining tothe slide images is often necessary or at least desirable. This is notonly true for slide images of technical, scientific or promotionalnature but also for slide-s of more personal interest. The enjoyment ofviewing slides will often be greatly enhanced by an accompanying commenton the situation or location depicted on the slide.

While movie film with sound track is well known, both for amateur andprofessional use, there are not available as far as the applicant isaware, any means for directly associating a slide or other stillphotograph with .a recorded sound message.

Accordingly, one of the principal objects of the invention is to provldenovel and improved means associating a slide and a sound track carrierfor simultaneous projection and sound reproduction respectively.

A more specific object of the invention is to provide common holdermeans for holding a slide and a sound ,track carrier in position forsimultaneous projection and sound reproduction respectively.

The term slide as used herein, is intended to encompass single pictureslides and stereoscopic slides both for .black and white and for colorprojection.

Further objects, features and advantages of the invention will bepointed out hereinafter and set forth in the appended claims formingpart of the application.

The holders according to FIGS. 1 to 19 inclusive, have in common thateach of the holders shown in the respective figures provides means forsupporting a slide, either of the single picture type or thestereoscopic type, and .a sound track carrier in a spatial relationshipsuch that upon insertion of the holder in an appropriately designeddevice, the slide and the sound track are held in operation'al positionsfor simultaneously projecting the slide and reproducing the intelligencerecorded by the sound track. As explained before, such an arrangementaccording to the invention causes in effect the slide to tell its ownstory when it is projected thereby giving the showing-of slides a newimpetus and making it more interesting and informative.

Referring firstto FIGS. 1, 2 and 3 in detail, the holder according tothese figures comprises a frame 25 made as shown of sheet metal or anyother suitable material such as plastic. The frame has a slide ortransparency receiving portion 26 and a sound track receiving portion.27. To form these portions, the frame may be dished and the resultingshallow pockets are closed with a back plate 28. The space in frameportion 26 is open at the long edges of the frame to permit theinsertion of a slide into said space. Windows 29 and 30 serve to permitprojection of a slide inserted in frame portion 26. The slide may bevisualized as a conventional slide in which the film proper is mountedin an appropriate frame made for instance of cardboard. The slide isretained in the frame by the margin of the slide frame extending betweenthe respective wall portions of frame 25. Thev slide may further bereleasably retained in frame portion 26 by V providing leafsprings 31.

and back plate 28. As can best be seen in FIG. 1, the

disc partly underliesturned over flanges 35 of the frame. It may becentrally rotated or by means of a roller engaging the periphery of thedisc. To permit such engagement, holder portion 27 is cut out at 36 and37.

As appears from the previous description and the figures, the holdersupports the slide and the disc in a sideby-side position and permitsinsertion of the holder with the slide and the disc in such position inone of the devices as shown in FIGS. 20 to 24 inclusive.

The holder according to FIGS. 4 and 5 is similar in principle .to thepreviously described holder.

The holder again comprises a slide receiving portion 26 and a discreceiving portion 27.

The slide receiving portion 26 forms a pocket for insertion of a slidewhich may be projected through windows 29 and 34 The recording disc 40is confined by edges of holder portion 27 but is otherwise free. Itrotates about pin 33.

The disc may be a disc for magnetic sound recording as has beendescribed in connection with FIGS. 1 to 3; it may also be a disc inwhich the sound is recorded by cutting of grooves as indicated by theinsert drawing associated with FIG. 5. Similarly a disc employingrecording grooves may also be employed in connection with the holderaccording to FIGS. 1 to 3.

As is apparent, the holder according to FIGS. 4 to 6 retains the slideand the recording disc in a side-by-side position in the same manner asthe holder of FIGS. 1 to 3.

The holder according to FIGS. 7, 8 and 9 is shown as a single pieceframe 41 made of plastic as indicated or sheet metal. The slidesupporting portion 42 of the frame is formed with preferably dove-shapedgrooves'44 and 45 for slidably receiving and retaining an aperturedcover piece 46. A Window 47 permits projection of an inserted piece offilm 51.

The sound track supporting portion 48 of the frame is integrated withthe sound recording and reproducing surface by forming the said surfacedirectly on frame portion 48. The recording surface may be amagnetizable layer formed with guide grooves 49.

A guide hole 50 may be provided to facilitate locating of the holder inthe slide projecting and sound reproducing device. In this arrangement,the sound recording and reproducing head rotates whereas the recordingsurface 48 is held stationary.

FIGS. 10 and 11 show a recording disc as may be used with either of theholders according to FIGS. 1 to 4 or with one of the holders shown inFIGS. 16 to 19 inclusive to be described hereinafter.

The disc according to FIGS. 10 and 11 comprises a non-magnetic metallicbase 55, a resilient layer 56 which may be made of felt, paper, rubber,rubber composition or suitable plastic and a magnetizable layer 57 madefor instance of suitable oxide sheeting. The three layers are cementedor otherwise bonded together, intermediate layer 56 forming a cushionfor the sound carrying layer 57. A guide hole 58 which may be in form ofa Maltese cross, serves to seat the record pin upon a drive shaft.

FIGS. 12 and 13 show a square shaped recording plate which comprises anon-magnetic base 60 preferably made of aluminum or plastic to which iscemented or bonded a layer 61 made of suitable rubber or plasticimpregnated with particles of magnetic material. A guide hole 62 servesto locate the plate in the holder.

The recording disc according to FIGS. 14 and 15 comprises a suitablemolded plastic base 65 carrying a recording oxide surface 66 in whichare formed guide grooves 67. The disc is provided with a Maltese crossshaped drive opening 58.

The holder according to FIGS. 16 and 17 is similar in principle to theholder according to FIGS. 1, 2 and 3, except that it is designed for astereoscopic slide. Accordingly, the slide supporting frame portion 26'is broadened to accommodate two pairs of Windows 29, 3t) and 29 and 30for the two pictures of a stereoscopic slide. The arrangement of theholder and its function are obvious from the description of the holderaccording to FIG. 1.

The holder shown in FIGS. 18 and 19 employs an annular disc 52 carryinga magnetic recording surface and provided with a flange 52. The disc isfree to revolve about a slide holder part 53 provided with a centralopening 53' through which light is projected. Flanges 54 retain aninserted transparency holder in proper position. A flange 55 formed fromthe rear of holder part 53 holds the disc incorrect relation. In use,this holder functions essentially similarly to those previouslydescribed. The holder is retained in the projector aperture by any suit-21. ably locating surface such as the outer portions of flanges 54. Thedisc is driven preferably by a friction roller which engages theperiphery of flange 52'.

As previously mentioned, all the aforedescribed holders and recordingdiscs therefor are designed for coaction with a slide projecting andsound reproducing device.
